The best jigging line today.

PE2.0 = 40lb (18.0kg)
PE2.5 = 50lb (22.7kg)

It is the strongest PE against tension and friction today. It enables you to go lighter without losing the strength.
It doesn’t stretch. Less than 1.0%, while most PE line stretches about 4%. That promises the direct control of the jig. Durability is excellent too.
This line is braided in a specific way, Tough Cross technology. One of the characteristics is that it doesn’t catch as much water as other PE line, so that it also supports your light and direct control of the jig.
